Letters and Papers 1517. 20 Aug 1517. R.O. 3608. SPINELLY to BRIAN TUKE.
Wrote yesterday with a packet for the Bp. of Helna, &c., and of a bill refused him by Galterotte on account of the sickness. Is in great favor there, and in a condition to do Wolsey effectual service. The wind is S.W. All things are aboard ready for a fair wind, which is expected about the opposition of this new moon. Begs he will see his patent sealed. Chievres told him the French had resolved to send Albany to Scotland, and he will take his passage by Brittany. In Chievres' absence the Lord Montayny will write to the Bp. of Helna. The Prince Palatine has left in disgrace because he presumed to write a letter to the Lady Eleanora, the King's sister, without the knowledge of the King, desiring her to marry him. The letter got abroad, and, though it was very honest, Chievres prevailed to have him punished for his presumption. The Prince is still there. News has come from Rome. The Lord of Nassau has killed divers Almains in the service of the Duke of Gueldres lying in the villages. Is to advertise Wolsey of the news, except touching the Lady Eleanora. Begs he will send him the man he spoke of. Middelburg, 20 Aug. 1517.

Has got her a lodging by my Lord Cardinal's means, such as could not have been found hereabouts "for all causes," as the bearer will explain. Nothing more can be done in our other affairs, nor can all dangers be better provided against, so that I trust it will be hereafter to both our comforts; but I defer particulars, which would be too long to write, and not fit to trust to a messenger till your repair hither.

Pepy's Diary. 20 Aug 1665. Lord's Day. Sir G. Carteret (age 55) come and walked by my bedside half an houre, talking and telling me how my Lord is in this unblameable in all this ill-successe, he having followed orders; and that all ought to be imputed to the falsenesse of the King (age 35) of Denmarke, who, he told me as a secret, had promised to deliver up the Dutch ships to us, and we expected no less; and swears it will, and will easily, be the ruine of him and his kingdom, if we fall out with him, as we must in honour do; but that all that can be, must be to get the fleete out again to intercept De Witt, who certainly will be coming home with the East India ships, he being gone thither. He being gone, I up and with Fenn, being ready to walk forth to see the place; and I find it to be a very noble seat in a noble forest, with the noblest prospect towards Windsor, and round about over many countys, that can be desired; but otherwise a very melancholy place, and little variety save only trees. I had thoughts of going home by water, and of seeing Windsor Chappell [Map] and Castle [Map], but finding at my coming in that Sir G. Carteret (age 55) did prevent me in speaking for my sudden return to look after business, I did presently eat a bit off the spit about 10 o'clock, and so took horse for Stanes, and thence to Brainford to Mr. Povy's (age 51), the weather being very pleasant to ride in. Mr. Povy (age 51) not being at home I lost my labour, only eat and drank there with his lady, and told my bad newes, and hear the plague is round about them there. So away to Brainford [Map]; and there at the inn that goes down to the water-side, I 'light and paid off my post-horses, and so slipped on my shoes, and laid my things by, the tide not serving, and to church, where a dull sermon, and many Londoners. After church to my inn, and eat and drank, and so about seven o'clock by water, and got between nine and ten to Queenhive, very dark. And I could not get my waterman to go elsewhere for fear of the plague.

On 20 Aug 1868 the Irish Mail train collided with goods wagons. The force of the collision derailed the engine, its tender and the leading guard's van. Two runaway wagons next to the brake van, which carried 50 wooden barrels, holding about 1,700 gallons of paraffin oil caught fire. The engine, tender, guard's van and the first three-passenger carriages were instantly enveloped in dense smoke and flames, which soon spread to the fourth carriage and the front of the leading post office van. This prevented any immediate attempt to rescue the occupants of the first four carriages, who all died.
